Question

which gas in the atmosphere protects living things from ultraviolet light?
carbon dioxide
water vapor
oxygen

Explanation:

Ozone (\(O_3\)) in the stratosphere forms a layer that absorbs most of the Sun's harmful ultraviolet (UV) radiation. Carbon dioxide (\(CO_2\)) is a greenhouse gas, water vapor (\(H_2O\)) also contributes to the greenhouse effect and weather, and oxygen (\(O_2\)) is essential for respiration but does not protect against UV light.

Answer:

ozone
